Speedfox 01/02 - Lockbody Exchange
Some Speedfox 01 and 02 models have lateral play on the Trailsync dropper seat post. This lateral play can sometimes be associated with a seized lockpin on the dropper post mechanism which results in malfunction / bad performance.
Please note that this is not a safety issue. Although not meeting BMC performance standards, it is safe to ride those bikes until they are treated. The problem is solved by replacing the Trailsync lockbody and lockpin. This takes around 15 minutes and can be done by a qualified mechanic (see instructions manual).
